Q ROYAL E. DEANE, OF BROOKLYN, NEW YoR'K.

Letters Patent No. 90,934, dated June 8, 1869.

DRAUGHT-REGULATOR FOR HEATING- APPARATUS The Schedul referred to inthese Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, ROYAL E. DEANE, of Brooklyn, Kings county, New York,have invented, made, and

. applied to use a new and useful Draught-Regulator forHeating-Apparatus; and I do declare the following to be a full, clear,and correct description of thesame, reference being bad to theaccompanying drawings, making part of this specification, and to theletters of reference marked thereon, in which- Figure 1 is a sideelevationof my draughtregulator.

Figure 2 is a longitudinal section of the same.

Figure 3 is a transversesection of the same.

In the drawings, like parts of the invention are designated by the sameletters of reference.

The nature of the present invention consists in certain improvements, asmore fully hereinafter set forth, in the construction of adraught-regulator for heatingapparatus'for heating dwellings and otherbuildings,- the object of the invention being .the production of adraughtregulator that shall be reliable in its operation,.and oneconstructed at a low cost.

To enable those skilled in the artsto make and use my invention, I willdescribe the construction and oporation of the same.

A shows an oblong box or case, formed of any suitable metal, in whichare contained the operative parts of my apparatus, which box or case hasone end closed, while the opposite end may he left open, and upon thesides of which box or case, placed centrally, are the openings B, inwhich are inserted two collars, through which pass the pipes leadingfrom the heating-apparatus and to the chimney.

Within this case or box A is placed a secondary case or-box, Q, madeconsiderably smaller than the case or box A, so that there shall he acertain amount of spaceintervening btween the interior of the outer caseA and the exterior surface of the inner case 0.

The interior case 0 is provided with a steam-chainber, D, formed byenclosing a portion of it beneath a curved plate of metal, E, whichextends from its rear end very nearly to its bottom or lower surface,the portion of said inner case not so enclosed being intended moreparticularly as a water-chamber.

F "shows a door, hinged to the rear end of the case A, so that it mayreadily be'opened or closed, as hereinafter set forth and G is' aconnecting-rod, connecting said door with or to a standard, H, the lowerend of which is inserted in a wheel, held upon a spindle, free to movein the plates '11, attached directly upon the exterior of the curvedplate of metal E.v Upon the lower side of this wheel is secured one endof a curved rod, J, the opposite end of which is secured upon the upperside of a float, K.

This float K is simply a hollow hemispherical body of metal, madesufficiently large to be easily acted upon by .water, as more fullydescribed.

To the forward end of this float is attached one end of a chain, L, theopposite end of which is attached to the rear end of a lever, M,suspended in the ears 0, upon the water-supply pipe 1?; The forward endof this lever M opens or closes the valve Q placed at the rear end ofthe water-supply pipe P, for the purpose hereinafter described.

It shows a cover, which, that the apparatus may operate efliciently,shouldfii lightly over that portion of the inner case 0 in which thewater-chamber is placed; and in the side of this cover, so thatcommunication may be had with the interior, is inserted a pipe, S, theuse of which will be hereinafter explained.

The apparatus maybe placed uponthe pipe leading from aheating-apparatus, so that the gases arising from the consumption of thefuel. contained therein may pass into the outer case, and thence aroundor beneath the inner or secondary case 0, and, having performed theirfunction, shall pass out of or away from the case or box A, through anopening upon the opposite side, through a pipe inserted in'this opening,to the chimney.

7 Having been so positioned, and the water-supply pipe having beenconnected with a water-tank, or other means to supply water, the cock Tis opened, the inner or secondary case supplied with water, which waterrises in the water and steam-chambers to the height of the cock T, andthe cock is closed.

As the gases arising from the consumption. of fuel in the furnace enterthe outer case, they either pass around or beneath the steam-chamber,heating the water in the same, until steam is produced, when the waterin said chamber is depressed, and the water in the water-chamber iselevated, and, acting upon the I float, raises the same.

As the float is raised, it, through the curved-rod standard andconnection, opens thedoor, admitting a volumeof air into the case or boxA, thus checking the draught by the air admitted between the flue andthe fire-chamber. As the air enters the box or case A, the exterionofthe steam-chamber is cooled, and, as the steam is condensed, the floatpreviously elevated is depressed, and, as it falls, the door connectedto the same, as shown, is closed.

When, from any cause, the water contained in the inner or secondary casefalls below the water-line, and it becomes necessary to resupply waterto the same, the float, in its descent, causes the forward-eud of theleverM to be elevated, opening the valve upon the water-supply pipe, andallowing a suificient quantity of water to enter the inner case or box,and, when this quantity of water is supplied, this valve is closed bythe rising of the float to the surface of the same.

Thus, it will be seen, that in the construction of the apparatus,provision is made both for the'opening and closing of the door, and forasupply of water to the same.

While the apparatus is in operation, the evaporation arising from theinner case passes through the pipe S into the furnace, this pipe beingcontinued so as to communicate with the same, and mingles with the hotair supplied to the apartments.

While I have spoken of the steanbohamber as dependent upon the gasesarising from the consumption of fuel, I am aware that, in some cases,steam may be supplied to generate steam in the steam-chamber, withoutchanging the nature of myinvention.

This means of generating steam in the steam-chamber may be used byconnecting the steam-chamber with a steam-generator.

Having thus described my invention,

What is claimed as new, is-

1, The combination of a steam-chamber, float, and door, connected to thefloat in any convenient manner,

when the same shall be constructed and operate substantially as and forthe purposes set forth.

2. Combining, with the float, the lever operating the valve of thewater-supply pipe, substantially as and for the purpose set forth.

ROYAL E. DEANE.
